Many Sur Ron and Segway riders are looking for a longer rear fender to prevent mud, dirt, and sand form being caked on their back when riding offroad. The first model of fender brought to market was great for this, but thats about it, over time it would begin to sag and not fit the body lines as well. The GritShift V2 fender has solved this issue, By including the stock seat tabs, and allowing the plastic and metal mounting points to both be attached to the factory seat this has greatly strengthened the fender and added rigidity. We are very impressed with the new fender as we have already flipped a bike on a hill climb with no damage or change to the integrity of the bracket or fender.
